YouTube on Hover Preview addon incompatible?
« on: March 23, 2018, 01:44:41 PM »
I installed the addon YouTube on Hover Preview
https://addons.mozilla.org/en-US/firefox/addon/youtube-on-hover/?src=search

However, it does not work.  Is it incompatible or is something else preventing it from functioning.
